At the sessions held at the Old Bailey on the 31st of October, the prisoner was indicted for the offence with which he stood charged, and the jury returned a verdict that he was guilty. His defence consisted only of a denial of the facts alleged against him, and he heard the finding of the jury delivered without much emotion. At the conclusion of the session he received sentence of death, in common with the other capital convicts; and he then urged upon the court the improbability of the charge, and suggested that his condition was such as to render it most unlikely that for the profit which he should derive, he should commit so diabolical an offence. The unfortunate man subsequently made representations to government, with a view to procure a commutation of his sentence; but although considerable exertions were made in his favour, an order for his execution on the 2nd of January 1827 was received at Newgate on the 20th of December. The wretched man, who had been constantly attended in jail by his young wife, was dreadfully affected at receiving the fatal intelligence.
The subsequent conduct of the convict was such as ill befitted his awful situation. The bare contemplation of the moment of execution completely unmanned him, and instead of applying himself to religious exercises, he sat day after day brooding over his past life, and occasionally starting upon his feet, bitterly inveighed against his sentence. He had from the time of his trial persisted in denying his guilt; but at length he confessed that he was rightly charged and convicted, pleading in excuse that he was of unsound mind at the time. On his finding that his execution was inevitable, he had recourse to many ingenious measures to procure his escape, and it was discovered that he had some powerful auxiliaries, both among his fellow-prisoners, and his friends without the jail. Ground for suspicion of the design was first given by an intercepted letter; and at this time the prisoner occupied a cell which, from its position, was most favourable for his project. It was situated close to the outer wall of the prison, and could he but have removed the iron bars of the window, he might easily have reached the parapet, by means of a rope ladder, and descended into Newgate street. A ladder was actually made of black sewing-thread, firmly and curiously wattled, which must have been the work of very considerable time: but the difficulty of removing the window-bars was found by the prisoner to be insurmountable without the aid of instruments. It is almost needless to say, that on the discovery of the scheme, the most minute watch was kept over the movements of the prisoner and his coadjutors. Frequent and anxious inquiries were observed to be made by White for a pair of shoes, which did not appear to be wanted; and when they arrived, they were examined; and spring saws, capable of cutting through iron bars without making any noise, were found sewed up between the upper and lower soles. The wretched man was now made acquainted with the frustration of his plans, and he at once admitted his intention, and spoke of the practicability of his scheme with much pride and satisfaction.
